These clauses neither benefit the tenant nor the LL. What usually happens is the the tenant will not address pending issues because they know it comes out of their pockets. So, they ignore repairs, hide them, or attempt their own. The end result is that what could have been a 50 dollar repair is now a 500 dollar repair. I think some of the free income late night gurus came up with the idea of capping LL and tenant repairs. Had your GF not have been responsible, she would have promptly contacted her LL of needed repairs.
